T0 ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL S..STARNES, ot' Macomb, in the county of McDonough, and State of Illinois, have invented a new and improved Plough; and I do hereby declare that thefollo'lwing is a full and exact description of the same, reference being had to the accompanying drawings, Aand to the letters of referencemarked l thereon. In the drawings-- i l l Figure 1 represents a side view of my plough,

Figure a back view, andv Figure 3 a front view'.v This invention consists of novel devices for regulating the depth and width of the cut made by aplough; l. i also, for adapting a plough to be drawn by a greater orless number of horses, andto'zbc used as a subsoil-plough l when desired, as will hereinafter more fully appear.v v

l To enable others to make and use my invention, I will now proceed to describe its construction and operation.` A represents a plough of ordinary construction in nearly all of its parts. Ono feature, however, peculiar to this plough, is the pivoted beam a, which swings, to a certain extent, on the standard b, suitably supported. by attachment to the handle c and thc share d. The standard is provided withia shoulder, b', at a iit point, between which shoulder andthe beam a, surrounding the standard, is a spiral spring', d. The uppereud ofthe staudard'b is provided with a'. screw-thread, on which, above the beam, works a nut,.e, with a handle. ,By screwing the nut upward, the spring is left free topress the beam upwardto a corresponding extent.V Thefhigherthe` `beam,.the deeper will be the cut.' This arrangement thnsfur'nishes the means for acut of any desired -`depth within certain limits. Y i i 4Another peculiar feature of my inventionris the lever h, pvoted to the cross-baume', and jointed, at its Alower end, to the inner end of the plough7beam a. Above and parallel with the cross-beam z' is a rack-bar, c, l between the teeth c of which the Alever h is placed in varioush positions. By means of this lever the ploughbeam'may be set at any angle,relatively to the share, within certain limits. A: i Q l` In proportion as the point of thebeam is more or less to the right of the share, the` plough will` make a narrow or wider cut. Therack-bar enables the beam to be xed at the desired angle. By throwing the beam` l well -to the right, three horses abreast can be used, one walking in the last furrow, and `the-othertwoon the, unbrolfcnsoil. On' arriving at the end of a furrow, if it be desired to run the' plough back in the same furrow, and thus convert it into a subsoil-plough, it will only be necessary to suitably swing thebeam, when this opera-` tion may be performed. i

Through the inner cud of the plough-beam passes the rod Z, fixed between the" ploughfhandles, below the" .i

cross-beam z'. Along this rod the end of the beam slides, when-moved from side to side, and when the beam is` thrown upward, the rod prevents the innerend from partaking of this motion,- whereby the outer end is raised higher.

'Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

i 1. The combination of the standard 6,'sprin-g d, rod l, and beam a, substantially as and for the purpose described. i v I 2. The combination of the lever k, rack-bar k, and plough-beam a, substantiallyfas and for the purpose` l i .l described.' v l SAMUEL S. STARNES' "i Witnesses:
